Here are what's probably 6 note pads.
Or booklets of some kind. Two are shaped/die-cut. The top seems to have a rounded area with a color Sonic in it, and the bottom is shaped like the outline of the ring/ribbon Sonic appears in. The top two have a line art portrait for Sonic on one, and Tails on the other. The Segasonic one IS a notebook for sure, which appears elsewhere on School Gear with it's details. But what's the middle one too? It has lots of detail, but the photo is pretty small to tell what's going on with it. You can write in for credit if you can clear up what these are.
